`ROLLER-BEARING.

SPECIFICATION forming part of Letters Patent No. 661,863, dated November 13, 1900. Application tiled September 4, 1900. Serial No. 28980. (No model.)

To @ZZ whom, it may concern.-

Be it. known that I, JOHN S. GODFREY, a citizen of the United States, and a resident of Harrington, in the county of Lincoln and State of Washington, have invented a new and Improved Roller-Bearing, of which the following is a full, clear, and exact description. y

This invention relates to improvements in roller-bearings for shafts, journals, or the like; and the object is to provide a rollerbearing of simple construction that will be strong and serviceable and in which friction is reduced to a minimum.

I will describe a roller-bearing embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views.

Figure lis atransverse section of a rollerbearing embodying my invention, and Fig. 2 is a section on the line x of Fig. l.

The casing for the bearing consists of an upper section l and a lower section 2, which is here shown as supported on a base 3. The two sections l and 2 are provided with outwardly-extended flanges through which fas- Within the casing is a steel lining, also consisting of two sections 5 6, the ends at the inner side of the lining being curved inward. A series of guide-rollers 7 are mounted to rotate on rods 8, which extend through the casing and have their ends attached to rings 9. The ,ends ofV the rods 8 are provided with shoulders which abut against the inner sides of the rings 9, and

nuts l0 are engaged with the outer or pro# jected ends of said rods. It is to be understood, however, that the outer ends may be riveted, if desired. By providing the shoulders on the rods, which abut against the inner sides of the rings, the cage or holder for the rollers 7 is prevented from rocking or twisting lnovement that would cause the ends of the rollers to bear tightly against the rings. It will be noted that the ends of the rollers 7 are rounded, so that they have very little bearing on the rings. Vertical rollers 1l are supported by the rollers 7, as plainly indicated in the drawings, and then engage against the steel lining of the casing. The ends of these rollers ll are rounded or made semicylindrical, thus causing very little if any friction at the end portions engaging with the curved portions of the lining. These several rollers ll form a bearing for the shaft or spindle l2.

An oil-port 18 communicates with the interior of thecasing at the bottom, and oil may be supplied thereto froma cup l-t. The oil passing into the lower portion of the casing will be taken up bythe friction-rollers as they rotate and will be carried to the top and circulate downward, and a portion of the oil will pass through ports l5, formed in the guide-rollers 7,to the rods 8, thus lubricating the bearing for the roller.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A roller-hearing, comprising a casing having the ends of its inner wall curved inward, a cage, guide-rollers supported by said cage and extended through the casing, the ends of said guide-rollers being rounded, and antifriction-rollers supported by the guiderollers and having rounded ends, substantially as specified.

2. A roller-bearing, comprising a casing, a hard-metal lining therefor having its ends curved inward, a cage, comprising rings adapted to surround a shaft or spindle, rods connecting the rings, the said rods being provided with shoulders to bear against the innersurfaces of the rings, guide-rollers mounte'd to rotate on the said rods and provided with oil-ports, means for supplying oil lo the interior of the casing, and friction rollers supported by the guide-rollers and having rounded ends, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN S. GODFREY.
